Acquisition to Facilitate Growth in Network Services and e-Commerce Solutions

Arlington, Va., March 16, 2000 -- CACI International Inc (NASDAQ: CACI) announced today that it will soon consummate a purchase of substantially all of the assets of Century Technologies, Inc. (CENTECH), a privately-held information technology (IT) company based in Maryland. Expected to close on or about April 1, 2000, the acquisition will further enhance CACI capabilities in network services and e-commerce for the company's existing federal, state & local, and commercial client base. The acquisition also fits CACI's strategic plan for rapid growth in the state & local market. The terms of the acquisition were not disclosed; the transaction will be financed through bank borrowings.

CENTECH is headquartered in Silver Spring, Maryland, with facilities in Texas, Ohio, and Oklahoma. The company focuses on high-level IT services in the areas of networking and telecommunications, e-commerce, geospatial technologies, and software engineering. CENTECH revenues for its fiscal year ending March 31, 1999 were $23.7 million, up 16% from 1998.

CENTECH's business base centers upon clients from the federal government, state governments, and the military services.

(Jack) London, CACI Chairman and CEO, stated that "CENTECH's exceptional client relationships are well known throughout our industry, and we feel they are a great match for CACI's own client-focused culture. This acquisition supports CACI's growth strategy in our key lines of business of network services and e-commerce. CENTECH's delivery of high-level IT services also fits nicely with our strategic plans, particularly since CENTECH provides these services to key clients in valuable vertical markets in both the government and private sectors. We expect the transaction to be accretive to our earnings within the first twelve months. We welcome the outstanding talents of CENTECH employees."
